The blocks awarded to the Company are located in the Foz do Amazonas
Basin (one block) and in the Pará-Maranhão Basin (two blocks) in the
northern deep water of offshore Brazil, and have a total area of
approximately 2,300 km2 gross (1,153 km2 net) (See attached map). The blocks were acquired in consortiums that
include as partners the companies Queiroz Galvão Exploração e Produção
S.A. ("QGEP") and Premier Oil PC ("Premier"). All three blocks have an
initial five year exploration phase with the option to extend the
exploration phase by an additional three years.

Ronald Pantin, Chief Executive Officer of Pacific Rubiales commented:
"We are very pleased with the results of the Bid Round and the
acquisition of these high potential blocks. This strengthens and
consolidates our position in the Equatorial Margin basins of South
America, which we started to build with our investment in CGX Energy
Inc. (which has blocks in Guyana), as well as our position in Brazil`s
offshore Santos Basin, where we have had recent oil discoveries. We
are also pleased to be partnered with QGEP, which is one of Brazil`s
largest oil companies and with Premier, a global oil producer."
